Speaking before last month's strike action, Unite regional officer Simon McCartney said: “Workers now face the imposition of changes to their rosters leaving them out of pocket and rearranging their family life. To add insult to injury bus workers have also found themselves short changed when doing overtime on a rest day.

“Our members take great pride in keeping London on the move 24 hours a day and deserve better. Tower Transit management needs to start listening to its workforce and adopt a more constructive approach by engaging positively with Unite to resolve this dispute.”
